Porous acupuncture needle

Abstract

A porous acupuncture needle includes a needle portion for puncturing the outer skin of human body, and an operation portion for being held and handled by a user. The needle portion includes a needle body, a porous layer formed by a plurality of micropores on the surface of the needle body, and a charge layer covering on the surface of the porous layer. When performing acupuncture, the affinity provided by the charge layer makes the human tissues to attach to the needle portion more easily. Moreover, during twirling the needle, the porous layer also increases the capability to affect the surrounding tissues and therefore the stimulation to the acupuncture point.

1 . A porous acupuncture needle, comprising a needle portion for puncturing the outer skin of human body, and an operation portion for being held and handled by a user, characterized in that:
 the needle portion comprises a needle body, a porous layer formed by a plurality of micropores on the surface of the needle body, and a charge layer covering on the surface of the porous layer.   
     
     
         2 . A porous acupuncture needle as claimed in  claim 1 , wherein the micropores are communicated with each other for forming the porous layer to be a three-dimensional porous structure. 
     
     
         3 . A porous acupuncture needle as claimed in  claim 1 , wherein the charge layer is a negative charge layer. 
     
     
         4 . A porous acupuncture needle as claimed in  claim 3 , wherein the charge layer is a negative charge layer of hydroxyl groups. 
     
     
         5 . A porous acupuncture needle as claimed in  claim 1 , wherein the micropores respectively have the diameter ranged from 20 to 1000 nm. 
     
     
         6 . A porous acupuncture needle as claimed in  claim 1 , wherein the porous layer has a thickness ranged from 50 to 5000 nm. 
     
     
         7 . A porous acupuncture needle as claimed in  claim 1 , wherein the porous layer has dielectric constant ranged from 2 to 110 F/M.
